Harvard-Yenching Library will expand the Rare Book Reading Room on the 3rd floor during the month of June, 2015. Because of this project, books in the first three rows of stacks on the 3rd floor (call numbers J 110 – J 1876.4), which cover Chinese classics, Philosophy, and Religion up to Japanese esoteric Buddhism (Mikkyo) in Yenching classification will be temporarily moved to the sub-basement (a floor under the basement). Some of these books will be moved to the Harvard Depository and the rest will be moved back to the 3rd floor by the end of the summer. The sub-basement stacks are open stacks and are freely accessible.
